YTA and BT200
IMPORTANT • Analog output may change temporally in
connecting with BRAIN terminal due to an initial current flowed to it. To prevent communication signal affecting the upper system, it is recommended to install a lowpass filter (approximately 0.1s).
• Communication signal is superimposed on analog output signal. It is recommended to set a low-pass filter (approximately 0.1s) to the receiver in order to reduce the output effect from communication signal. Before online-communication, confirm that communication signal does not give effect on the upper system.
WARNING
Do not attempt to use the BT200 in a dangerous environment where explosive gas or inflammable vapor is generated.
The BRAIN communication signal is superimposed onto the 4 to 20 mA DC analog signal. Since the modulated wave is a communication signal, superimposing it on the normal signal will, from basic principles, cause no error in the DC component of the analog signal. Thus, monitoring can be performed via the BT200 while the transmitter is on-line. As shown in Figure 2.1, there are two methods of connecting the transmitter and the BT200: the first is to use the BT200 connection hook provided in the terminal box and the other is to use a terminal board or relay terminals on the transmission line.

3.2 Parameter Description The following outlines the setting items for YTA BRAIN protocol. Before starting operations, review the entire configuration of the transmitter to confirm that it meets the requirements of the current application.
• Checking Sensor Connection (→3.2.1)
• Sensor Configuration (→3.2.2)
Set the “sensor type” and “number of wire connections” of the sensor connected to the input terminal of the temperature transmitter. (Set the “sensor type” and “number of wire connections” of Sensor1 or Sensor2.)
• Process variable mapping (→3.2.3)
Process variable is to be assigned as primary (PV), secondary (SV), tertiary (TV) and quaternary (QV) Variables. They can be monitored on the integral indicator or by using the configuration tool. The process variable mapped to the PV is handled as the 4 to 20 mA DC output.
• Unit (→3.2.4)
An engineering unit of “degC” or “K” (Kelvin) can be chosen for process variables. When voltage value or resistance is specified as an input type, the unit is automatically set as mV or ohms.
• PV Range (→3.2.5)
Change the range of PV [primary variable] to be output as the 4 to 20 mA DC. There are two ways to set the range value: Setting by keyboard, and setting by applying a value.
• Damping (→3.2.6)
Adjust the response time to smooth the output with rapid changes in input. The damping time constant of the process variable can be set from 1 to 100 seconds.
• Device Information (Tag number, writing in note) (→3.2.7)
Not only a tag number but also an optional memo can be set for each instrument.
• Test Output (→3.2.8)
This function can output any value as DC output. Use it for loop check. An output of any value between 3.6 mA and 21.6 mA can be set.
• Burnout Function (→3.2.9)
Configure the current output value of 4 to 20 mA DC if the input sensor circuit is opened or if the hardware has failed.
• Integral Indicator Display Mode (→3.2.10)
Allow to select items to be displayed on the LCD panel if the integral indicator is mounted.
• Write Protect (→3.2.11)
• Sensor trim (→3.2.12)
Correct the factory default characteristics to match the input signal.
• Analog Output trim (→3.2.13)
• Sensor Backup Function (→3.2.14)
When the Backup mode is selected, Sensor2 operates as a backup sensor of Sensor1. If the Sensor1 circuit is opened or if a problem occurs in this circuit, the signal output is switched to Sensor2 output automatically.
• Sensor Matching Function (→3.2.15)
If the transmitter has the optional specifications or CM1, the accuracy of the temperature transmitter can be improved by changing the specific sensor constants.
• CJC Selection (→3.2.16)
Select whether to use the terminal block temperature for cold contact compensation or to use the arbitrary constant set by the user.

3.2.2 Sensor settings When changing sensor type, it is necessary to change the parameters related to each sensor. Figure 3.1 shows both the wire connection to input terminals of the transmitter, and sensor type selection for parameters in each connection case. Note that thermocouples and voltage value input are categorized as Group A, and resistance temperature detectors and resistance are categorized as Group B. Check the connection between input terminals and temperature sensors, and set the correct sensor type and the number of wire connections in “Sensor1” or “Sensor2” (for 2-input model). The following shows the standard setup.
(1) Setting the sensor type
Set a sensor type using the following parameters.

NOTE If a sensor of Group A is used, the number of wire connections is automatically changed to “2 WIRE”. In such a case, it is not necessary to “set the number of wire connections” of Item (2) below. If “No connection” is set, a number of wire connections can be set, however, it is made invalid.
(2) Setting the number of wire connections
Set a number of wire connections using the following parameters. However, this setup is only required when the Group of the sensor type is “B”. This setup is not required for a sensor of Group A.
Setting item “Sensor1” parameter
Select a number of wire connections from the following options.
Sensor Option Remarks Sensor1 2 WIRE, 3 WIRE,
4 WIRE If “4 WIRE” is selected, “Sensor2” cannot be used.
Sensor2 2 WIRE, 3 WIRE
NOTE If “4 WIRE” is selected as the number of wire connections of Sensor1, Sensor2 cannot be used even for a 2-input model temperature transmitter. Therefore, the sensor type at Sensor2 side is changed to “No connection” automatically.
IM 01C50T03-02EN
3.2.3 Process variable mapping The YTA temperature transmitter can handle four process variables: primary variable (PV), secondary variable (SV), tertiary variable (TV), and quaternary variable (QV). These variables can be referred to as digital values through the BRAIN protocol. The PV value is processed for 4 to 20 mA output. (→ 3.2.5 Range Setting) Set Sensor1 and Sensor2 (for the 2-input model only) before starting the process variable mapping. (→ 3.2.2 Sensor Setup)
(1) Setting the mapping
The following explains the PV to QV setting. Mapping means the assignment of PV to QV inputs. Set the following parameters for mapping.
Variable Setting parameter PV B10:PV is SV B20:SV is TV B30:TV is QV B40:QV is
Select an input to be mapped as the mapping destination from the following options. Table 3.2 Mapping assignment list

NOTE An input related to Sensor2 cannot be selected for the 1-input model.
NOTE • When the user sets “Sensor1-Terminal”,
Sensor1 must already be set as a sensor (thermocouple or resistance temperature detector) to measure the temperature.
• When the user sets “Sensor2-Terminal”, Sensor2 must already be set as a sensor (thermocouple or resistance temperature detector) to measure the temperature.
• When the user sets “Sensor1-Sensor2”, “Sensor2-Sensor1”, “Average”, or “Sensor Backup”, Sensor1 and Sensor2 must be able to measure the same physical quantity (such as same temperature, the same DC voltage, and the same resistance).
If the above requirements are not satisfied, an “AL.60 Illegal PV Cfg” alarm occurs.
IM 01C50T03-02EN
3.2.4 Unit A unit of the terminal block temperature can be set for process variables PV to QV, Sensor1, and Sensor2 (the 2-input model only). Set the following parameters. When the unit is set, it is used to display the parameters that are shown in the “affecting parameters” column.
Target Parameter Affecting parameter PV B11:PV UNIT A10, E10 to 11 SV B21:SV UNIT A20 TV B31:TV UNIT A30 QV B41:QV UNIT A40 Sensor1 D13:SENSOR1

B51:TERM UNIT A50, H30 to 32, P14 to P15
Select a unit from the following options. Option Unit Description degC °C Degrees centigrade
K K Kelvin degF °F Degrees Fahrenheit degR °R Degrees Rankine
NOTE If the target unit is DC voltage, the unit “mV” is used to display the parameter values in the “Affecting parameters” column, regardless of the above unit setting. Similarly, the unit of resistance is set to “ohms”.
NOTE The units of PV to QV are fully independent of the units of Sensor1, Sensor2 (for 2-input model only), and terminal block temperature. For example, even if Sensor1 is mapped to the PV, the unit used for PV display is the unit that has been set by “B11:PV UNIT”. It is not affected by the unit of “D13:SENSOR1 UNIT”.
3.2.5 Range Setting The range setting refers to assigning an output range of 4 to 20 mA to an area (LRV to URV) within the PV digital output range (LSL to USL).
F0303.ai
4 mA (0%)
20 mA (100%)
However, the following restrictions apply when setting the range.
• Both LRV and URV must be within the range between LSL (lower limit of the sensor measurement range) and USL (upper limit of the sensor measurement range).
• The width of LRV and URV must be greater than the minimum span of sensors.
For the measurement range and minimum span for each sensor type, see Chapter 7 “Standard Specifications” in IM 01C50G01-01EN document.
NOTE If the PV value is outside the range of LRV to URV, the current below 4 mA or the current above 20 mA is output. In this case, the output is calculated in the same ratio. However, even in this case, the upper and lower limit values of the current to be output are limited to the range between the computation output lower limit value and the computation output upper limit value.
NOTE The LRV can also be set to a value larger than URV. In this case, the output is inverted, and the output current falls when the PV value increases.
(1) Setting LRV and URV
There are two ways to set the LRV and URV: by entering LRV and URV numeric values directly, and by providing real input.
a) Specify LRV and URV directly as numerical values.
Directly set the LRV and URV using the following parameters. The unit specified by “B11:PV UNIT” is used.

DEL CLR ESC
1. Select “E11:URV”, and press [ENTER].
2. Enter value “150”, and press [ENTER] twice.
3. Press [OK]. <Setting has completed.>
Note: Units specified in “B11:PV UNIT” are used. If the unit is changed by B11, the units used in E10 and E11 are also changed.
Example: Change the measurement range from “0 to 100°C” to “0 to 150°C”.
b) Changing the range by applying an actual input Enter a value in the transmitter, and set the PV value in the LRV or URV unit. Use the following parameters for unit setting.
Setting target Setting parameter LRV E12:AUTO LRV URV E13:AUTO URV
The following shows the procedure. 1. Give the input equivalent to LRV to the
transmitter and stabilize it. 2. Select “EXEC” from “E12:AUTO LRV”, and
press the [ENTER] key twice. 3. The value set as LRV is displayed. Confirm it,
and press [OK]. 4. Similarly, set the URV using “F13:AUTO URV”.
NOTE With E12 and E13, after execution by selecting EXEC, the system returns to the NO EXEC state automatically.
(2) Setting the calculation output lower limit and calculation output upper limit
Set the calculation output lower limit and calculation output upper limit by using the following parameters.

3.2.6 Damping time constant This function adjusts the response speed against sudden input fluctuations in terminal block temperature, Sensor1 and Sensor2 digital outputs, and 4 to 20 mA analog output. The terminal block temperature and Sensor1 and Sensor2 damping settings are also reflected on the PV to QV digital outputs, which are their mapping destinations. There are two types of damping setting items: the damping time constant, and the damping calculation threshold. Of these, the damping calculation threshold is set only by damping of analog output.
The following shows the target of damping setting and its setting parameters.
Setting target Damping time constant
Damping calculation Threshold
Terminal block temperature
(1) Setting the damping time constant
The temperature transmitter calculates 63% of the input range to be output after the time period set by the damping time constant has elapsed. The damping time constant can be set between 0 and 100 seconds (an integer). If set to 0 seconds, damping is skipped.

(2) Damping calculation threshold
The temperature transmitter does not perform damping if the variation amount is larger than the damping calculation threshold. However, this function is only effective for damping of analog output. The damping calculation threshold is set by the percentage (%) that is relative to the output range (the output change rate per calculation cycle). This threshold can be set between 0 and 99% (an integer). If set to 0%, damping is skipped.

It is only the date recording function. There is no built-in clock function, and the date is not updated.
3.2.8 Test Output The constant current of 3.6 mA (2.5%) to 21.6 mA (110%) can be output from the temperature transmitter. This function is useful for performing the loop check.
The following shows the setting parameters related to the test output.
Parameter Settings Remarks F10: OUTPUT MODE
Switches between Test Output and Normal Output.
NORMAL MODE: Normal Output
MANUAL MODE: Test Output

Also reflected in F20
Set the release time of Test Output.
10 MINUTES 30 MINUTES 60 MINUTES 3 HOURS 6 HOURS 12 HOURS
* Either F20 or F21 can be set, and they are reflected mutually.
IMPORTANT • The Test Output by the forced output function
is automatically canceled 10 minutes (it is changeable by F30:RELEASE TIME setting) after changing to MANUAL MODE. Even if the power of the configuration tool is turned off or if the communication cable is disconnected during test output execution, the Test Output state is maintained.
• If you wish to cancel the Test Output immediately, select the NORMAL MODE with “F10:OUTPUT MODE”. Also, when the temperature transmitter is turned off, the Test Output is canceled.
• If “I30:OUTPUT” is set to 4 mA or 20 mA, the MANUAL MODE cannot be set using F10.
NOTE If the temperature transmitter has the integral indicator, “TEST” is displayed in the lower row along with its output level (% indication) during test output. Also, “AL.70” alarm (Output Man Mode alarm) is generated during Test Output. This informs that the Test Output is in progress; this is not abnormal.
3.2.9 Burnout Function
(1) Setting the output state at sensor burnout
If a sensor mapped to the PV value is broken or if it has become disconnected from the terminal, you can set the output state.
The following shows the setting parameters related to the sensor burnout.
Parameter Settings Remarks E40: BURN OUT
Operation setting of burnout function
HIGH (21.6 mA) LOW (4 mA) USER (The value
set in E41 or E42)
OFF (Hold with previous output value)
E41: BURN OUT mA
Specify the burnout output in mA when “USER” is selected.
It is also reflected in E42
E42: BURN OUT %
Specify the burnout output in % format when “USER” is selected.
Also reflected in E41
* Either E41 or E42 can be set, and they are reflected mutually.
If a sensor is burnt out, alarm AL.09, AL.10 to AL.13, or AL.22 occurs.
CAUTION If the sensor burnout is set to OFF, it is held by the previous output value, however, at this time a time lag before the sensor abnormality is detected. Therefore, the current outputs according to the abnormal measured value (the value set by “I40:NRML MIN OUT” or “I41:NRML MAX OUT”). Be sure to understand this point when setting to “OFF”.
(2) Display of output state of hardware abnormal value
Parameter name Display Description
HIGH: 110% (21.6 mA)
LOW: -5% (3.2 mA)
The output state at hardware abnormality setting can be set by the slide switch of the MAIN assembly.

3.2.10 Integral Indicator Display Mode If the temperature transmitter has an integral indicator, you can set the display items and the updating cycle.
F0307.ai
(1) Setting the display items
The integral indicator can display up to four channels (Disp Out1, Disp Out2, Disp %, and Disp mA, except for alarm indication). Of these, Disp % is “% of RANGE”, and Disp mA is a dedicated channel of “mA of RANGE”. As the display content is fixed, you can only specify ON or OFF. Any process variables PV to QV can be specified for “Disp Out1” and “Disp Out2”. One of the process variables must always be specified for the “Disp Out1” channel. The “Disp Out2” channel can be set not to display by setting it to “Not Used”.
Table 3.1 shows process variables that can be specified for each display channel.
Display channel
Process variable
Disp Out1
Disp Out2
The following shows the setting parameters of each display channel.
Display channel
Disp Out1 J20:DISP1 VRBL Select from PV to QV.
Disp Out2 J22:DISP2 VRBL Select from PV to QV, or “Not Used”.
Disp % J30:% DISPLAY Select from ON or OFF.
Disp mA J32:mA DISPLAY Select from ON or OFF.
(2) Selecting the decimal-point position
You can specify the position of the decimal point (the number of digits displayed after the decimal point) for each display channel. Specify the number of display digits (an integer from 0 to 3) after the decimal point.
Display channel Decimal-point position Disp Out1 J21:DISP1 POINT Disp Out2 J23:DISP2 POINT Disp % J31:% POINT Disp mA J33:mA POINT
(3) Setting the display cycle
Set the display switching cycle. When the time corresponding to the preset display cycle has elapsed, the following information is displayed. Set the cycle using the “J50:DISP CYCLE” parameter. Select the “HIGH”, “MID”, or “LOW” cycle.
Selection value Display switching cycle HIGH 1200 ms MID 2400 ms LOW 3600 ms
(4) Setting the display information
When the numerical information of each display channel is displayed on the upper part of the display meter, the information attached to the process variable can be displayed in the lower row. To display the incidental information, turn the display ON or OFF using the following parameters. This setting is valid for all display channels.
Setting parameter Incidental information J10:D INFO PARM Process variable name J11:D INFO UNIT Unit of process variable J12:D INFO STYPE Sensor type J13:D INFO SWIRE Number of sensor wire
connections
IM 01C50T03-02EN
The display order is switched in the following order for each display cycle.
Process variable
2400 ms (Can be set by "J50: DISP CYCLE" parameter)
F0308.ai
If the display setting is turned OFF, the incidental information display is skipped. If the display of many items of incidental information is turned ON, it will take a long time to shift to the next display channel.
(5) Setting the bar graph display
When “Disp %” and “Disp mA” channels are being displayed, and when the display target of “Disp Out1” and “Disp Out2” is PV, a bar graph is displayed at the top of the display panel. You can see the appropriate percentage of that level relative to the output range. Set the bar graph display by turning the “J40:BAR GRAPH” parameter ON or OFF.
NOTE If there is an abnormality in the transmitter or sensors, if their settings are incorrect, or if the measured value deviates from the range, an alarm is generated. If an alarm has occurred, the last display channel is indicated, and the generated alarm number and name are displayed. If burnt out, a bar graph is displayed regardless of “J40:BAR GRAPH” parameter setting.
3.2.11 Write Protect This function disables parameter writing, and protects the data set in the temperature transmitter. The Write Protect function can be set in one of the following three ways.
1. Slide switch of MAIN assembly
When the slide switch is set to the ON position, protection is enabled. When set to the OFF position, the protection is canceled. The protection cancel state continues until this function is turned ON again. See Section 3.2 “Burnout and Write Protect Switch when Hardware Error Occurs” of IM 01C50G01-01EN.
2. Setting using integral indicator
You can enable the protection by setting a password using “WRT.PRT” of Local Parameter Setting.” If the protection is already set, write protection is released when the same password is entered again in the “WRT.PRT”. The protection cancel state continues until a password is set by “WRT.PRT”. For the local parameter setting, see Section 3.4 “Local Parameter Setting” of IM 01C50G01-01EN.
3. Setting by BRAIN parameter
You can enable the protection by setting a password using “G42:NEW PASSWORD”. When a password set by G42 is entered in “G41:WRT ENABLE” parameter, write protection is released. The protection cancel state continues for 10 minutes only. However, if the parameter is written via BRAIN protocol, it will continue for 10 more minutes from that point. This chapter focuses on this method.
The temperature transmitter holds the above three as the independent state. If any one of them is set, it enters a protected state and no parameter can be written.
NOTE Although the three protection states listed above are kept as independent states, the procedure to individually check those states is complicated. Therefore, when using multiple methods in combination, special attention is required to manage the protection information of each instrument.
(1) Checking the status
You can check the current write protection state using the following two methods. However, you can check the protection state of the entire temperature transmitter. You cannot check the three setting states individually as described above.
Check by parameters:
Parameter Value Description G 4 0 : W R T PROTECT
NO Not protected (Parameter writing enabled)
YES Protected (Parameter writing disabled)
Checking by integral indicator:
If the integral indicator is mounted, you can check the write protection state by reading an indication of a key symbol as shown below.
Not protected Protected F0309.ai
(2) Setting the password and write protection
The following explains the BRAIN parameter settings. When you set a password, write protection must be canceled. Check the write protection state using the method described in (1) “Confirmation of state”. If the system is protected, release the protection first.
Write the desired password in the following parameter.
Parameter Password Remarks G42:NEW PASSWORD
Eight blank characters
This is a special password. If this password is set, write protection is always canceled, and the protection status is maintained until another password is set.
Other than the above
Write protection is enabled. The protection is maintained until the password, that has been set by “G41:WRT ENABLE” parameter, is written.
This set password is only displayed on the confirmation screen immediately after it is set. After that, the eight blank characters are always displayed during normal parameter reading.
Confirmation screen immediately setting
Normal display F0310.ai
PARAM G42:NEW PASSWORD G43:SOFT SEAL KEEP G60:SELF CHECK GOOD DATA DIAG ESC
SET G42:NEW PASSWORD ABCDEFGH
The password can contain the following characters and symbols only.
% $ # “ !
(3) Releasing write protection
The following explains how to cancel write protection if it has been set by the BRAIN parameter. The write protection cancel state continues for 10 minutes only. However, if the parameter is written via BRAIN protocol, it will continue for 10 more minutes from that point.
Write the desired password in the following parameter.
Parameter Password G41:WRT ENABLE
Write the same password as that specified by “G42:NEW PASSWORD” parameter.
Immediately after writing the password in the above parameter, the confirmation message is displayed on the screen. You can check the success or failure of protection release by reading this message.
Message Description Released Protection was canceled successfully Rejected Protection failed to cancel (due to incorrect
password) Blank Protection has already been canceled,
or the password contains eight blank characters.
F0311.ai
IM 01C50T03-02EN
NOTE If you wish to set the protection state back to the protection state, do not write the parameter for 10 minutes and wait until the protection state is set again. However, if a new password is set for “G42:NEW PASSWORD”, the protection state is set immediately.
NOTE If an incorrect password is entered in “G41:WRT ENABLE”, the state that existed before the password was entered is maintained (the protection is not released from the protected state, and the canceled state is maintained if it has already been released).
NOTE If “G40:WRT PROTECT” remains YES (or the key mark of the integral indicator remains displayed) even though “Released” is displayed on the confirmation screen, protection has been set by the slide switch of the MAIN assembly or by the integral indicator. It will be necessary to release protection using each method separately.
NOTE If you forget your password, you can temporarily cancel the write protection function using the “Joker” password. For the “Joker” password, contact Yokogawa sales office.
(4) Software Seal
If the write protection function is canceled by using the “Joker” password, it can be identified by the Software Seal function. You can check the Software Seal state by reading the following parameter.
Parameter Value Description G43:SOFT SEAL
KEEP The seal is not broken (“Joker” password is not used)
BREAK The seal is broken (“Joker” password is used)
NOTE The broken software seal state is maintained even after the unprotected state using the “Joker” password ends. To return to the KEEP state again, it is necessary to cancel protection by using the password that was set G42:NEW PASSWORD.
3.2.12 Input Adjustment The YTA temperature transmitter is adjusted prior to factory shipment based on the standard characteristics of sensors, and the process variables are output with these characteristics. The input adjustment is made to correct both the shipping characteristics of the temperature transmitter and the internal calculation value of input signals. (See Figure 3.4.) Even when the input adjustment is made, the characteristics that exist during factory shipment are retained. Therefore, the characteristics can be restored during factory shipment.

The following explains the Sensor1 input adjustment. For input adjustment of Sensor2, read the parameters based on the above table.
(1) Connect the calibration equipment to the temperature transmitter in an stable ambient temperature environment, and warm up for three or more minutes. (See Figure 3.5. For Sensor2 adjustment, check wiring methods (b) and (c) of Section 5.4 “Connecting Cables and Terminals” of IM 01C50G01-01EN.)

(3) Check the output value of Sensor1 from “I11:SENSOR1”. (Presence or absence of difference with expected value for input of (2))
(4) Write the expected value for input of (2) to “I12:S1 ZERO ADJ”. Example: When input corresponding to a temperature of 0°C is given to Sensor1, write “0” in “I12:S1 ZERO ADJ”.
The 1-point adjustment ends in Step (4). For 2-point adjustment, perform Steps (5) and (6).
(5) Now, adjust the span. Apply the input, that corresponds to the span adjustment value, to Sensor1.
(6) Write the expected value for input of (5) to “I13:S1 SPAN ADJ”.
NOTE When “EXEC” is written in the “I16:S1 ADJ CLR” parameter (or when “EXEC” is written in “I26:S2 ADJ CLR” for Sensor2), the user adjustment is reset to the default characteristics. After the reset, this parameter value is returned to “NOEXEC”.
IM 01C50T03-02EN
3.2.13 Output Adjustment The Output Adjustment function adjusts analog output values. When a precision ammeter (for calibration) is connected, when the 0% and 100% are output, and if there is a deviation in PV value, the Output Adjustment is executed. Use the following parameters for adjustment purposes.
Parameter Usage I30:OUTPUT Sets the Output mode. Set the analog
output to NORMAL (Normal Output), 4 mA, or 20 mA.
I31:OUT ZERO
I33:OUT ADJ CLR
[Adjustment method]
(1) Write “4 mA” in “I30:OUTPUT”, and output 4 mA current.
(2) Read the actual output PV value using the precision ammeter for calibration.
(3) Write the PV value that was read in Step (2), in “I31:OUT ZERO”. If only the zero-point adjustment is required, skip Steps (4), (5) and (6), and proceed to Step (7).
(4) Write “20 mA” in “I30:OUTPUT”, and output 20 mA current.
(5) Read the actual output PV value using the precision ammeter for calibration.
(6) Write the PV value that was read in Step (5), in “I32:OUT GAIN”.
(7) Write “NORMAL” in “I30:OUTPUT”, and return to the normal output.
3.2.14 Sensor Backup (for the 2-input model only)
If Sensor1 has failed, the Sensor Backup function automatically uses Sensor2 as output. Even if Sensor1 is recovered during backup operation, Sensor2 will continue to be used until the backup operation is reset by the parameter or by switching the power OFF. If Sensor2 has failed during backup operation, the temperature transmitter generates an AL.24 “Backup Sns2 Fail” alarm and outputs the sensor burnout.
(1) Setting the sensor backup function
(1) Set the “sensor type” and “number of wire connections” of Sensor1 and Sensor2. If Sensor1 and Sensor2 must measure the same target (both should measure the temperature or voltage).
(2) Set an alarm mask appropriately. Setting
parameter Target Alarm
AL.24 Backup S2 Fail
NO MASK NO MASK
IMPORTANT Always set “K10:S1 FAIL MASK”, “K11:S2 FAIL MASK”, “K23:BKUP S1 MASK”, and “K24:BKUP S2 MASK” parameters to NO MASK. To activate the Sensor Backup function even if the sensor short-circuit is detected, set "K12:S1 SHRT MASK" and "K13:S2 SHRT MASK" to "NO MASK". If the Sensor Backup function is not required when a short-circuit occurs, set them to "MASK".
CAUTION After Sensor1 has failed, a time lag occurs until the transmitter detects it and switches to Sensor2. During this time, the value measured by failure Sensor1 is output as the PV value. The current output is indefinite (however, it is within the range between the calculation output lower limit and the calculation output upper limit). After that, the failure sensor is switched to Sensor2, and the current corresponding to the value measured by Sensor2 is output.
(3) Set the PV mapping to the Sensor Backup function. Setting
parameter Setting value

For details about mapping, refer to Section 3.2.3. "Process variable mapping".
IM 01C50T03-02EN
(4) Execute the parameter of the Sensor Backup return instruction. Setting
parameter Setting value Remarks
G21:RETURN S1
EXEC After execution, the system returns to the NO EXEC state automatically.
(2) Checking the sensor backup state
To check the backup state, read the following parameter.
Parameter Value Remarks G20:BACKUP ST
N/A Sensor Backup function is disabled. (Sensor1 and Sensor2 are used to measure the different targets.)
SENSOR1 The temperature transmitter outputs an input of Sensor1.
SENSOR2 The temperature transmitter outputs an input of Sensor2.
(3) Returning from the backup status (Release of “AL.23 Backup S1 Fail” alarm)
Even if Sensor1 is recovered to the normal operation state during backup operation (an “AL.23 Backup S1 Fail” alarm has occurred), the temperature transmitter outputs an input of Sensor2 until the backup operation is reset by the parameter or by switching the power OFF. To return the output back to the Sensor1 input, execute the parameter of the Sensor Backup return instruction.
Setting parameter
G21:RETURN S1
(4) Releasing the “AL.24 Backup S2 Fail” alarm
When the Sensor Backup function is enabled and if Sensor2 has failed, the temperature transmitter outputs an input of Sensor1 as it is, however, an “AL.24 Backup S2 Fail” alarm occurs. To release this failure, follow the procedure below. (1) Recover Sensor2 (by repairing wiring, replacing
the sensor, and other measures). (2) Execute the parameter of the Sensor Backup
return instruction. Setting
G21:RETURN S1
3.2.15 Sensor Matching Function This function is only available when optional specification/CM1 is specified. The sensor matching function sets specific sensor constants in the temperature transmitter to significantly improve the temperature measurement accuracy.
(1) Sensor matching function of YTA710
The properties of the RTD sensor for the YTA 710 comply with the standard specified in IEC 60751. As the characteristics of the RTD sensor, there are variations within the range permitted by the standard, and they may cause measurement errors. The Sensor Matching function improves the precision of temperature measuring by programming the Callendar-Van Dusen constants, specific numbers defined for each RTD sensor, in the temperature transmitter. The following relationship exists between the resistance (Rt) of a RTD sensor and the temperature (t) at that time.
Rt = R0 {1 + α (1 + 0.01δ) t - t2 - (t - 100) t3 }αδ 104
αβ 108
i where, Rt=Resistance (ohms) at temperature t (°C) R0=Sensor-specific constant (Resistance at 0°C) α (alpha)=Sensor-specific constant δ (delta)=Sensor-specific constant β=Sensor-specific constant (0 if t>0°C) The exact values for R0, α, δ and β are specific to each RTD sensor, and are obtained by testing each individual sensor at various temperatures.
Generally, constants A, B and C are also used as the characteristic coefficients of the RTD instead of α, δ and β. The relationship is described as follows.
Rt = R0 {1 + At + Bt2 + C ( t - 100 ) t3 }
ii where, Rt=Resistance (ohms) at temperature t (°C) R0=Sensor-specific constant (Resistance at 0°C) A=Sensor-specific constant B=Sensor-specific constant C=Sensor-specific constant (0 if t>0°C)
These two equations are equivalent. Model YTA710 can cope with either case (α, δ and β, or A, B and C) as above mentioned.
IMPORTANT • This function is only effective when the sensor
type is set to “Sensor Matching”. • Enter the appropriate R0 value corresponding to
the sensor type. For example, if you are using the Pt100, enter a value of approximately 100 Ω for R0.
(2) Setting the sensor matching function
(1) Set a sensor type. Set a sensor type and a number of wire connections using the following parameters.
Setting Item
Set them according to the actual number of wire connections.
(2) Setting of Sensor Matching constant Set each constant using the following parameters. However, only one pair of A, B and C or one pair of α, δ and β must be set. The other pair is calculated automatically by the temperature transmitter, and it is set automatically.
Constant Parameter for S1
+ 100.00 ohms
+ 100.05 ohms
D46:S2 BETA
E-1 (10-1)
+1.08634 E-1
+1.00000 E-1
IMPORTANT When entering R0, α, δ, β, A, B, C in the YTA, the following restrictions apply.
• α, δ, β, A, B and C must be normalized with the value of the exponent determined for each constant. The number of decimal places that can be entered is five. Since the position of the decimal point is fixed, pad it with zeros if lower digits are unnecessary. (See the above setting example.)
• The decimal point can be set arbitrarily for R0. However, the input possible range is from +0.0000 to +32000.
NOTE If a value that has significantly deviated from the factory default value is set for each sensor matching constant, an “AL.07 Temp R-Calc Fail” alarm may occur. In such a case, set the correct constant again or change the sensor type (to Pt100 for example). In either case, the temperature transmitter needs to be restarted afterwards.
3.2.16 CJC Function Selection For thermocouple input, the terminal temperature measured by an internal sensor of the temperature transmitter is used for Cold Junction Compensation function (CJC function). The constant value set by the user can be used for the compensation function in place of the measured terminal block temperature.
Set the CJC function in the following procedure. (1) Mode selection of CJC function Select a mode of CJC function by the following parameters.
Parameter Setting value Remarks
Internal CJC Perform cold junction compensation at terminal block temperature.
Constant CJC
IM 01C50T03-02EN
NOTE If you have selected the internal CJC, the settings in Steps (2) and (3) are not required.
(2) Unit setting of cold junction compensation temperature
Set the unit of cold junction compensation temperature using the following parameters.
G11:CNST CJC UNT
degC Set the cold junction compensation temperature in degrees of centigrade (°C).
K Set the cold junction compensation temperature in Kelvin (K).
degF Set the cold junction compensation temperature in degrees of Fahrenheit (°F).
degR Set the cold junction compensation temperature in degrees of Rankine (°R).
(3) Setting of cold junction compensation temperature
Set the cold junction compensation temperature using the following parameters.
Parameter Setting range Remarks
-40 to 85 degC
When units other than degC are set in (2), the setting range is the value converted from the temperature shown on the left to the setting unit.
<4. Self-Diagnostics> 4-1
IM 01C50T03-02EN
4. Self-Diagnostics The temperature transmitter continually monitors its own performance during normal operation. If an error occurs, it displays and records the error in the logging parameters and the output vale that is off the scale, and with the integral indicator, an alarm number corresponding to the error is displayed, etc.
4.1 Checking for problems An alarm occurs when there is a problem with functions. The alarm can be checked with the parameter number of each item “A to L, O to P, R 60: SELF CHECK”. In addition, this SELF CHECK parameter is indicated as a binary value of GOOD or ERROR. If an ERROR is shown, select the SELF CHECK parameter, read it, and display the alarm details.

NOTE While the Sensor Backup function is active, if both AL.23 Backup S1 Fail and AL.24 Backup S2 Fail occur, sensor burnout will occur. For details about sensor backup refer to Section 3.2.14 "Sensor Backup Function".
IMPORTANT If S1 Failure, S2 Failure, S1 Short, S2 Short, Term Sensor Fail, Backup S1 Fail, and Backup S2 Fail are masked, the sensor burnout due to these events is also suppressed. If it is necessary for the sensor burnout event to occur, release the alarm mask (NOMASK setting).
4.2 History Functions The YTA710 temperature transmitter has the following history functions.
(1) Alarm history
(1) Number of history records Up to 59 history records are stored in the temperature transmitter memory, and any five of them can be referred to simultaneously. If more than 59 records are stored, history records will be deleted in order starting from the oldest and overwritten by new history records.
(2) History data buffer The same 59 history records are held in the buffer that is constantly updated and in the parameter display buffer of the temperature transmitter. Before displaying the parameters, synchronize the parameter display buffer with the buffer that is constantly updated. Then, update them to the latest information. Execute the following parameters to synchronize the data.
Parameter Option Remarks P18:AL LOG UPD
NO EXEC
Nothing occurs even if this value is written. In normal circumstances, this value is displayed.
EXEC When this value is written, the buffers are synchronized explicitly. When synchronization has finished, the system returns to the NO EXEC state automatically.
IM 01C50T03-02EN
NOTE Also, the buffers are synchronized when the temperature transmitter is turned on.
(3) History number Up to 59 records are assigned with history numbers 0 to 58. The record assigned history number 0 is the latest one.
(4) Parameter Display window The Parameter Display buffer holds all 59 data records, however, it holds only five display parameter records. Therefore, you can select and display any five records out of the 59 records. The selected five records are called records of the “Parameter Display window”. The five records of the Parameter Display window are called LOG1 to LOG5 (and LOG1 has the latest record).

Set the following parameters to set up the Parameter Display window.
P19:AL LOG NO
0 to 55 Specify a history number to position the beginning of the Parameter Display window. The fifth record from the history number you specified is the Parameter Display window. If “55” is specified, the LOG5 is made invalid.
(5) Log data The log data of LOG1 to LOG5 consists of the alarm data and the time information at this time. When the following parameters are read, the log data is displayed.
Parameter Description P20:ALARM LOG1 Alarm data of LOG1 P21:LOG TIME1 Record time of LOG1 P22:ALARM LOG2 Alarm data of LOG2 P23:LOG TIME2 Record time of LOG2 P24:ALARM LOG3 Alarm data of LOG3 P25:LOG TIME3 Record time of LOG3 P26:ALARM LOG4 Alarm data of LOG4 P27:LOG TIME4 Record time of LOG4 P28:ALARM LOG5 Alarm data of LOG5 P29:LOG TIME5 Record time of LOG5
The alarm data of P20, P22, P24, P26 and P28 is the same as obtained by A to L, O to P, R 60:SELF CHECK of each item. The recording time of P21, P23, P25, P27 and P29 is equivalent to the period of time when the transmitter is shipped from the factory and when the transmitter operating time (until LOG1) is recorded. The operating time is displayed in “DDDDDdHH:MM” format. “DDDDD” is the number of days. The number of digits may increase or decrease within the range of 1 to 5 days according to the actual number of days. “HH” is hours, and “MM” is minutes.
(6) Empty log data Although the maximum number of history records is 59, in actuality, less than 59 records may have been recorded, such as when the operating time span from when the temperature transmitter was started is short. In such a case, unrecorded logs may be included, depending on the setting of the Parameter Display window. At this time, the value of recording time parameters (P21, P23, P25, P27, and P29) is blank for the data of unrecorded logs. Therefore, it is possible to judge the validity of log data using these values.
(2) History of maximum and minimum measurement values
The maximum and minimum measurement values of Sensor1, Sensor2 (for the 2-input model only), and terminal block, obtained after factory shipment (or after these values are cleared) for each measurement value of terminal block temperature (TERM) have been recorded in the temperature transmitter. The maximum and minimum values can be checked by referring to the following parameters.
Item Sensor1 Sensor2 (2-input
P11:S1 VAL MAX
P13:S2 VAL MAX
P15:TERM VAL MAX
NOTE The above variables may become large due to sensor disconnection or others. If it occurs, clear them by following the procedure below.
Also, you can clear the maximum and minimum values of Sensor1 and Sensor2 (for the 2-input model only). If cleared, the subsequent maximum and minimum values start to be updated immediately. Use the following parameters to clear these values.
Parameter Option Remarks P05:LOG CLEAR
NO RESET The values are not cleared. This is usually used. System returns to this state after clearing of values.
RST SENSOR1
RST SENSOR2
Only Sensor2 is cleared. (It is displayed for the 2-input model only.)
RST S1&S2 Sensor1 and Sensor2 are cleared. (It is displayed for the 2-input model only.)
(3) Operating time
The operating time of the transmitter after factory shipment is shown. It can be checked using the following parameters.
Parameter Remarks P30:OPERATE TIME
The operating time is displayed in “DDDDDdHH:MM” format. “DDDDD” is the number of days. The number of digits may increase or decrease within the range of 1 to 5 days according to the actual number of days. “HH” is hours, and “MM” is minutes.
NOTE The operating time is saved in the non-volatile memory every 15 minutes.
IM 01C50T03-02EN
4.3 Self Check Function The YTA has the following self-check functions.
(1) Hardware failure
This function detects a failure of CPU, AD converter, memory and others.
(2) Sensor failure
This function detects an open circuit of sensors. The transmitter flows the current, and outputs an open-circuit alarm if the resistance exceeds the threshold. Parameter setting: Not required Alarm output: If the resistance exceeds the
threshold, an S1 Failure (AL.10) or S2 Failure (AL.11) alarm is output.
(3) Terminal block failure
This function detects an open circuit of CJC. The transmitter measures the CJC resistance and notifies of a terminal block failure if the resistance exceeds the threshold. Parameter setting: Not required Alarm output: If the resistance exceeds the
threshold, a Term Sensor Fail (AL.22) alarm is output.
(4) TC short-circuit (TC)
This function detects a short-circuit of the TC sensor. The transmitter flows current, and outputs a short-circuit alarm if the sensor resistance (S1 RP23 for L10, or S2 RP43 for L15) is below the threshold.
Set the threshold (resistance) using the following parameters. Threshold setting
parameter Alarm detected Remarks
S2 Short (AL.13) 2-input model only
NOTE In order to output the S1 (or S2) Short alarm, "K12:S1 SHRT MASK" and "K13:S2 SHRT MASK" must be set to "NO MASK". (The alarm is masked by default.)
(5) “RTD” or “ohm” short-circuit (for 3-wire/4- wire type only)
This function detects a short-circuit of the sensor during “RTD” or “ohm” measurement. If the sensor resistance drops below the threshold (L11: S1 RC1 to L14: S1 RC4, L17: S2RC4, L16: S2RC4), a short-circuit alarm is output.
The threshold is fixed to 5 Ω, and parameter setting is not required. Threshold setting
Not applicable S1 Short (AL.12) Not applicable S2 Short (AL.13) 2-input model
only
NOTE • The alarm mask must be released in order to
output the S1 (or S2) Short alarm. (The alarm is masked by default.)
• In the case of 3-wire RTD or ohm connection, if actual connection and connection setting are imbalanced, an unforeseen alarm may be generated.
(6) RTD Corrosion (for 3-wire/4-wire type only)
This function detects any corrosion between terminal block and measurement cables. If the resistance between the terminal block and cables (L11:S1 RC1 to L14:S1 RC4, L17:S2 RC3, L16:S2 RC4) exceeds the threshold, a corrosion alarm is output.
Set the threshold using the following parameters. Threshold setting
L21:S1RTD COR TH
S1 Corrosion (AL.14)
L23:S2RTD COR TH
S2 Corrosion (AL.15)
2-input model only
NOTE The alarm mask must be released in order to output the S1 (or S2) Corrosion alarm. (The alarm is masked by default.)
(7) Sensor drift (for 2-input model only)
When the difference between Sensor1 and Sensor2 temperatures exceeds the threshold, a Sensor Drift alarm is output. When the temperature at the same position is measured by two sensors, this alarm indicates that there is a problem with either Sensor1 or Sensor2.
Set the threshold using the following parameters. Setting
parameter Settings Target alarm Remarks
L30:DRFT TH UNIT
AL.25 Sensor Drift
Threshold Set this parameter after unit setting.
NOTE If the threshold (L31:DRFT THLD setting value) is “0.0”, self-checking is skipped. Sensor1 and Sensor2 must be the sensors to measure the same physical quantity.
(8) Temperature cycle diagnostics
This function displays the number of temperature fluctuations that may cause the sensor to fail. This function is only enabled when the Sensor Type is set to TC or RTD. It indicates how many times the temperature alternately hits (or crosses) the upper and lower limits. The number of times, that exceeds the upper temperature threshold (L45:T CY UP VAL) and that exceeds the lower temperature threshold (L44:T CY LO VAL) (or when the value exceeds the upper temperature threshold after exceeding the lower temperature threshold) is counted. If this count (L40:T CY S1 CNT, L41:T CY S2 CNT display values) exceeds the alarm judgment threshold, a temperature cycle alarm (AL.26 S1 Temp Cycle, AL.27 S2 Temp Cycle) is output.
Check the current settings and state using the following parameters.
Parameter Description Remarks L43:T CY VAL UNT
Sets the upper/ lower threshold temperature unit.
The unit to be used for L44 and L45 setting.
L44:T CY LO VAL
L45:T CY UP VAL
L46:T CY AL TH Sets an alarm judgment threshold.
If it is set to “0”, self- checking is skipped.
L40:T CY S1 CNT
Displays the Sensor1 round trip count.
If this count exceeds the L46 set value, an “AL.26 S1 Temp Cycle” alarm is output.
L41:T CY S2 CNT
Displays the Sensor2 round trip count.
For the 2-input model only If this count exceeds the L46 set value, an “AL.27 S2 Temp Cycle” alarm is output.
L42:RST T CY CNT
The count can be reset for Sensor1 and Sensor2 separately.
NOTE If the alarm judgment threshold is 0, the temperature cycle check is skipped.
